What urine output target should be achieved in the emergent phase?

• A. 20 mL/hr
• B. 30 mL/hr
• C. 40 mL/hr
• D. 50 mL/hr

Answer: (B)

In the emergent phase after a burn, the priority is to restore intravascular volume so organs, including the kidneys, stay perfused. Urine output is a direct, practical measure of renal perfusion and overall fluid resuscitation effectiveness. A target of about 30 mL per hour for an average adult corresponds to roughly 0.5 mL/kg per hour, which is the standard benchmark used to guide fluid resuscitation and prevent under- or over-resuscitation. Clinically, you monitor hourly urine output (often via a Foley) and adjust IV fluids to maintain that rate, while also watching vital signs and other perfusion indicators. If output falls below target, increase fluids per protocol; if it exceeds target, reassess for over-resuscitation and adjust accordingly.
